Two years ago, a nine-month-old boy was gunned down at his grandmother’s home in Georgia on the eve of Mother’s Day, suffering the horrifying consequences of an escalating gang skirmish.

Now, gang leader Kenneth Eric Jackson is facing a slew of criminal charges for ordering the murder of KenDarious Edwards Jr., who died in his mother’s grasp as they hid from their attackers in a bathtub.

Jackson — the local head of Sex Money Murder, a gang affiliated with the Bloods — allegedly ordered the hit from behind bars with a smuggled cellphone in Georgia’s Autry State Prison. He was indicted Tuesday in DeKalb County, Georgia, on counts of malice murder, felony murder, aggravated assault and violating the state’s Street Gang and Terrorism Act, according to a report in the Atlanta Journal-Constitution.

“It is about as terrible a thing as I’ve seen in 17 years as a prosecutor,” DeKalb County district attorney Robert James told the newspaper.

Prosecutors say KenDarious was killed as a retaliatory measure, after the infant’s uncle — Oslushsla Smith, another member of Sex Money Murder — violated gang protocol by participating in the “unauthorized” murder of a 17-year-old woman, out of concern that she would report a previous killing to the police.

The woman’s body was found on May 10, 2014, and later that day, three men broke into a home on To Lani Farm Road and fired a series of bullets at KenDarious and his mother. Tanyika Smith survived, but suffered lasting eyesight damage after being struck eight times.

Christopher Florence and Marco Watson face the same charges as Jackson for their role in the attack, while Devin Thomas was convicted of KenDarious’s murder last November and sentenced to life in prison.
